ZEN4 AM5 LGA1718 pin package shown, more PCIe lanes and possible higher TDP

by Hilbert Hagedoorn on: 05/26/2021 08:39 AM | source: Executablefix (Twitter) | 45 comment(s)

We've already talked a bit about Socket AM5 and the new LGA Design over the weekend, but Twitter user ExecutableFix now also posted a photo of what the backside of such a processor would look like.

The photo is a mockup of ZEN4 and brings a look as to what the line-grid array (LGA) package would look like. Alongside the photo, he also gives a little more detail, as AMD's 'Raphael' would handle the new memory DDR5 standard. Also, the Zen 4 architecture would get 28 PCIe 4.0 lanes, four more than their predecessors. He also mentions an increased TDP, right now he's listing it at 120W, in the future that could be 170W as a possibility as well perhaps for specific high perf SKUs.

All this information falls into the realm of rumors though, so please treat them as such.

No more bent pins....on the CPU.
However, although a rumour, I can see it happen AMD going for a LGA socket.

28 PCIe lanes would probably be 16+4+4+4 (Chipset link) or 16+4+8 (Chipset Link)

I can see the chipset link going to x8, if the chipset is PCIe 4 capable, like X570 is.
X670 might have more lanes, if they use a smaller process node to produce it.

I guess it is a logical step. Although, I can't explain why, but socketing an LGA CPU just doesn't feel as satisfying.

About time. I had a heart attack when I ripped my 3900X out of the socket not knowing it was still stuck to my heatsink. I've built more computers than most people ever will, by luck never had a build not boot up and never screwed anything up during the build process, and yet I'm still terrified of holding/installing a CPU with pins since I've seen how easily they can be damaged.

Doesn't the existing AM4 socket support more than 32 PCIe lanes anyway???
